Always get them to bury themselves before dropping your intentions.

My wife is currently dealing with her employer and their complete lack of handicap spots, despite over 200 regular car spaces scattered all around a warehouse lot. She doesn't quite get how to "play the game" like this but she's learning.

One party recording state so I'd like her to go in to talk about it while recording, but her anxiety is completely stonewalling her from bringing it up.

Hit record on the phone, slip it in a pocket that has good clearance for the whole conversation, and get them to say the things they've said when they think nobody else can hear them.

Apparently the front office woman screamed at her to move her car (she parked there because the offices are isolated from traffic and have access to her work area)and "it's not our goddamn problem we don't have handicap spots, it's yours so deal with it"

I'm about to just skip around waiting for her to do things and file a complaint with the EEOC or at least the ADA government site complaint form. I'm sure that would take months, if not years before anything ever happened, but I can't hold her hand and be there when she confronts the owners about their 6-8 missing handicap spots.
